水平分型脱箱造型线易错箱
The modeling line of horizontal parting detachable box is easy to misplace
由于水平分型脱箱造型线自身设计的原因,铸件易产生错箱。对于新的设备而言,不考虑模具因素的情况下,产生错箱的原因如下:
Because of the design of the horizontal parting line, the casting is easy to produce wrong box. For the new equipment, without considering the mold factor, the causes of wrong box are as follows:
①定位砂箱或模板的销、套磨损较快,影响定位精度,应定期检查,及时更换。
① The pin and sleeve of positioning sand box or formwork are worn fast, which affects the positioning accuracy. It should be checked regularly and replaced in time.
②推型速度过快,导致上下型移位。上下型合箱后由造型机内合箱工位推向辅线,通常为保证生产线的效率,速度较高。特别是造型线运行时间较长,辅线上运输小车的车轮磨损而造成小车上平面低于合箱工位时,这种错箱的现象会更严重。
② The pushing speed is too fast, resulting in the up and down type displacement. After the upper and lower closure, the inner closure station of the molding machine is pushed to the auxiliary line, usually to ensure the efficiency and high speed of the production line. Especially when the molding line runs for a long time and the wheels of the transport trolley on the auxiliary line are worn, which causes the upper plane of the trolley to be lower than the closing position, the phenomenon of wrong box will be more serious.
③辅线运输小车的定位过于简单,个别类型的造型线上运输小车甚至就没有设计定位。定位精度不高,套箱中心与砂型中心很难保证重合,直接导致套箱时会碰触上型,形成上型移位,造成错箱。
③ The positioning of the auxiliary line transport car is too simple, and some types of modeling line transport cars even have no design positioning. The positioning accuracy is not high, so it is difficult to ensure the coincidence between the center of the casing and the center of the sand mold, which will directly cause the casing to touch the upper mold and form the upper mold displacement, resulting in the wrong box.
④如果运行小车上面的积砂不及时处理干净,砂胎在运行过程中受阻过大导致错型。
④ If the accumulated sand on the running trolley is not cleaned in time, the sand tire will be blocked too much during the running process, resulting in wrong type.
⑤套箱侧面如果有积砂,会造成套箱与模板中心不重合而造成错箱。
⑤ If there is sand on the side of the casing, it will cause the center of the casing and the formwork not to coincide, resulting in wrong casing.
⑥型砂在输送过程中不少公司的传送是敞开的,会导致水分蒸发量过大,型砂性能下降,特别是夏季。在传送带上用护罩密封,可减少水分的蒸发。
⑥ In the process of molding sand transportation, many companies open their transportation, which will lead to excessive evaporation of water and decrease of molding sand performance, especially in summer. The conveyor belt is sealed with a shield to reduce the evaporation of water.
